Equivariant strongly projectively flat maps of compact homogeneous K\"ahler manifolds

In this paper we define strongly projectively flatness of holomorphic maps into the complex Grassmannian manifold, which is a kind of generalization of holomorphic maps into the complex projective space and prove a rigidity of equivariant strongly projectively flat maps of compact simply connected homogeneous K\"ahler manifolds.

A Study of Submanifolds of the Complex Grassmannian Manifold with Parallel Second Fundamental Form

We prove an extension of a theorem of A.Ros on a characterization of seven compact Kaehler submanifolds by holomorphic pinching to certain submanifolds of the complex Grassmannian manifolds.
